Annoying Amnesia The Dark Descent graphics glitch

[Thomas]

I am almost suspecting this might be a HW problem. As it works in the test but not in game, seems to indicate that it has some problem with several occlusion queries happening at the same time.

But perhaps there is some simple fix....

Have any of you tried a game like Doom 3 and see if that works? Doom 3 has lots of halos and use OpenGL. That would be really nice way to narrow it down.
